Tajan, from France, sells on 27 October 2017 a "Northern Dutch School, circa 1580, follower of Joachim Beuckelaer" vegetable market, a large work (114 by 174 cm) estimated at 15,000 to 20,000 Euro.
Some elements can be found by Aertsen, like the remarkable red hat of the man, or the headdress of the woman. Different versions of this work are in the Ludwig-Suermondt Museum and in the Stadel.
Other details like the oversized hat also appear in other Aertsen works, but may me more generic and less artist-specific. The work for sale is probably also not by Aertsen (or Beuckelaer), as the faces are too weak, but it is painted by a good artist anyway.
